CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 330,4:16l datedNovember 17, 1885.

Application filed June 1l, 1885. Serial No. 168,387. (No model.)

To all whom, it may concern:

Be it known that I, ADRAIN NUTTING, a citizen of the UnitedStates,residing at Greenville, in the county of Hunt and State of Texas,have invented new and useful Improvements in OarCouplings, of which thefollowing is a specification.

This invention relates to that class of carcouplngs in which thedraw-head incloses a IO pivoted dog or hook that is normally seated by aspring, and provided with a 'chain or other elevating device for raisingit from its engagement with the coupling-link.

The invention consists in certain peculiarities of construction, ashereinafter set forth, whereby are secured efficiency and reliability ofaction, with freedom from injurious jar or vibration in thecoupling-hook and its connections without impeding the necessary play 2cof the link.

In the annexed drawings, illustrating the invention, Figure 1 is avertical longitudinal section of my improved car-coupling. Fig. 2 is ahorizontal section of the same. Fig. 3 is avertical cross-section ontheline xx ofFig. 1.

Referring to these drawings, the numeral 1 designates a recesseddraw-head havingaflaring mouth, 2, and provided with verticalperforations 3,for receiving an ordinary couplingpin, if required. Inthe narrow portion of the draw-head is inserted a transverse pivot-pin,4, that forms a fulcrum for the coupling hook or dog 5, which restsnormally on the iioor of the draw-head or on the inserted end of alink,6, as the case may be. The inner walls ofthe draw-head mouth are formedin vertical and horizontal section, as shown in Figs. 1 and 2. It willbe seen that on each vertical side, as shown in Fig. 2, the innersurface of the draw- 4o head tapers or curves gradually backward to thepoints 7, and then curves inward more abruptly to form abutments -8,that limit the inward movement of the link. These abutments 8 arelocated on each side of the pivoted dog 5, about midway between itspivotal and free ends. The upper portion or roof of the draw-head isprovided with a nearly triangular recess 9, which is formedlongitudinally in the center of the approximately conveXed roof or.upper wall, 10, the form of which is shown by dotted lines'in Fig. 1.This recess 9 intersects in front the upper vertical perforations, 3,and at the rear it gradually merges with the narrow longitudinal recessl1, in which thecoupling-hook 5 is pivoted. The front portion of thelower wall or floor, 12, is inclined upward and inward, and providedwith a recess, 13, directly above the lower vertical perforation, 3.This recess 13 is for the reception ofthe hooked end 14 ofthecoupling-dog 5 when the latter is lowered. It will be observed, however,that the recess 13 is sufiiciently deep to prevent contact therewith bythe hooked point 14, which is thus preserved from injury by battering..EX- tending across the floor ofthe draw-head, at the rear upper edge ofthe recess 13, is a transverse ridge or projection, 15, which issufficiently elevated above the forward eX- tended portion of thehorizontal iioor of the longitudinal recess 11 to form a rocking pointfor the link, as hereinafter explained. The coupling hook or dog 5 isnormally seated by means of a spiral spring, 16, arranged in a verticaldiagonal recess, 17, formed in the roof ofthe draw-head. Thelower end ofthis spring 16 rests on the upper surface of the couplinghook 5, nearits i'orward end, and'is held in place by aguide-pin,18, insertedtherein. The coupling-hook may be raised against the action of thisspring, when required, by

means of a chain, rod, lor other elevating de vice attached in an eye,19, formed in the upper forward corner of said hook. By forming theforward end of the hook 5 with. a curved or rounded surface, as shown,it is capable of being raised automatically by the pressure of theentering link. An abutment, 20, for the forward end of the hook 5, isformed by the front lower edge of the recess 9, in which said hookmoves,said abutment thus serving to take the strain of the draft, andthereby relieving the pivot 4, on which the hook is fulcrumed.

It will be observed that the construction and arrangement of thesocketed draw-head and its accompaniments is such that they can bereadily detached,so that new hooks and springs can be substituted withease whenever reto drop to the required point.

quired.

In order to remove these partsit is only necessary to withdraw thepivot-pin 4, when the coupling-hook 5 and spring 16 will drop forward,and can be taken out at once. On reinserting the parts the spring 16 isfirst passed up into its socket or recess 17, the guide-pin 18 isinserted into the upper edge of the hook 5, and the latter is thenpassed into the draw-head and its inner end elevated behind the abutment20, at the forward lower end of the recess 9. By this movement theguide-pin 18 will pass readilywithin the lower end of the coiled. spring16, and at the same time the pivotal end of the hook 5 is brought intoposition to be engaged with its pivot-pin 4, which is passed through theside of the draw-head. The link 6, when engaged with only one draw-head,has its engaged end forced down behind the ridge or projection 15 by thepressure of the hook 5 and its spring 16. It is thus not only securelyheld from 4accidental disengagement, but has its outer end elevated atan angle Ausually sufficient to enable it `to engage readily with anopposing drawhead of greater height than the one with which it isalready connected. Should it, however, be necessary to connect with adraw-head of equal or less height, the outer end of the engaged link canbe readily depressed by simply elevating the engaging dog slightlythrough its attached chain, rod, or other device, so as to relax thepressure on the engaged end of the link and permit its free outer endWhen the train is in motion, the link will have a rocking movement orplay at each end on the ridges or projections 15, under the yieldingpressure of the spring-seated hooks or dogs. The iiaring side walls ofthe draw-head will alsov allow the link to have all necessary side playin turning curves or otherwise. The coupling-dog 5, however, beingpivoted in the narrow longitudinal recess 11, is thereby held fromlateral movement, and so affords a rm point of engagement and draft forthe link. As the free or hooked end of the dog5 is sufficiently deep orof sufficient length vertically to bear against the rear side of theabutment 20 at all times when engaged with a link, it is obvious thatthe draft will thereby be distributed, so as to relieve the pivot-pin 4of all injurious strain.

What I claim is- 4 1. In a, car-coupling, the combination, with arecessed draw-head having rear lower abutments to limit the backwardmovement of the link, a forward upper abutment to. take the pressure ofthe coupling-hook, and a transverse ridge or projection for the link torock upon, of a vertically-movable coupling-hook pivoted in a narrowrecessed portion of said draw-head, and aspring located in a diagonalrecess formed in the upper part of the drawhead and bearing on the upperside ofthe hook near its forward end, substantially as described.

2. In a car-coupling, the combination, with a draw-head having a narrowlongitudinal recess for receiving the pivoted end of a coupling-hook, anarrow triangular recess for permitting an upward swinging movement ofthe hook, an abutment or bearing for the forward end of the hook, rearabutment to limit the backward movement of the link, and a transverseridge on which said link can rock, of a pivoted coupling dog having averticallyswinging movement in the narrow triangular recess at the rearof the forward abutment, a spiral spring located in a diagonal recess inthe upper part of the draw-head and bearing on said coupling-dog nearits forward end, and

a guide-pin for said spring, substantially as f described.

3. In a car-coupling, the combination of the draw-head 1, having lowerrear abutments, 8, upper forward abutment, 20, triangular recess 9, anda recess, 13, for receiving the lower hooked end of a coupling-dog, thelink 6, the pivoted dog 5, carrying a guide-pin, 18, near its forwardend, and a spiral spring, 16, surrounding said guide-pin, substantiallyas described.

4. In a car-coupling, the combination of a recessed draw-head havingabutments 8 and 20, and a transverse ridge, 15, of a link, 6, adapted torock on said ridge, a pivoted coupling-hook, 5, carrying adiagonally-projecting pi'n near its forward end, and a spiral spring,16, arranged. diagonally above the couplinghook andsurrounding said pin,substantially as described.

5. In a car-coupling, the combination of the draw-head l, having anarrow longitudinal recess, 11, the upper recess, 9, lower recess, 13,transverse ridge 15, rear abutments, 8, and forward abutment, 20, thecouplinghook 5, pivoted in the narrow recess 1l and adapted to swingvertically in the recess 9, and with a hooked end for engaging therecess 13 and abutment 20, the link 6, and the spring 16 in recess 17,substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
